Definitions

  • the present invention relates to a plastics box of the type including:
  • the object of the present invention is to provide an upright which can be produced by injection-moulding technology, with the use of simple, two-piece dies without movable members.
  • each upright includes:
  • first and second rows of segments which are integral with the rib and have respective bearing surfaces constituting the opposed walls of the channels for housing the side edges of the flaps, the segments in each row being separated by spaces the heights of which, along the longitudinal axis of the rib, are equal to or greater than the heights of the segments in the opposite row, along the same axis, the bearing surfaces of the segments in each row facing the spaces between the segments in the opposite row.
  • the solution according to the invention provides a stable mechanical connection between the side walls of the box and the uprights without the need to form channels of undercut cross-section in the uprights. It is consequently possible to use simple two-part dies which can produce a very large number of pieces, for example, 25-50 for each moulding cycle. This solution also enables recycled or filled thermoplastics materials to be used. By solving the problem of the cost of the uprights, the present invention makes plastics boxes competitive with the wooden or cardboard boxes which are currently used widely for packaging fruit and vegetables.
  • FIG. 1 is a perspective view of a box according to the present invention
  • FIG. 2 is a perspective view of the upright indicated by the arrow II in FIG. 1, on an enlarged scale,
  • FIG. 3 is a perspective view of the upright, taken on the arrow III of FIG. 2, and
  • FIGS. 4 and 5 are sections taken on the lines IV--IV and V--V of FIG. 1.
  • a sheet of plastics material is constituted by a rectangular, central portion 2, to each side of which a foldable flap 4 is hinged.
  • the central portion 2 constitutes the base of a box and the flaps 4 form the side walls of the box.
  • the flaps 4 are hinged to the central portion 2 by recesses 6 of depths less than the thickness of the rest of the sheet 1. Both the central portion 2 and the flaps 4 have stiffening ribs 8.
  • the sheet 2 is produced by the compression-moulding of a material constituted by a thermoplastic matrix and by fillers formed from waste products which are difficult to recycle, for example, thermosetting plastics materials.
  • the flaps 4 are movable from positions in which they extend parallel to the central portion 2 to positions in which they are perpendicular to the portion 2.
  • the flaps 4 are kept in their second positions by four corner uprights 10 of plastics material, only one of which is visible in FIG. 1.
  • the upright 10 is constituted by a one-piece body of injection-moulded plastics material and has a central rib 12, the longitudinal axis A of which is perpendicular to the base 2 of the box.
  • First and second rows of segments, indicated 14 and 16 respectively, extend from the central rib 12.
  • Each segment is constituted by two portions, indicated 14a, 14b and 16a, 16b, which are arranged symmetrically with respect to the central rib 12.
  • the segments 14 in the first row are connected to a pair of lateral ribs 18 parallel to the central rib 12.
  • the segments 14 in the first row are separated by spaces 20, the heights H of which along the axis A are equal to or greater than the heights h of the segments 16 in the second row.
  • the segments 16 in the second row face the spaces 20 between the segments 14 in the first row. This arrangement of the segments enables the upright 10 to be produced by a two-part die without slides or the like.
  • the segments 14, 16 have respective parallel bearing surfaces 22, 24 between which two channels are defined for housing respective side edges 26 of two adjacent flaps 4.
  • the side edges 26 of the flaps 4 are inclined to the flaps 4 at an angle B greater than 90°.
  • the bearing surfaces 22 of the segments 14 in the first row are inclined in a manner corresponding to the inclination of the edges 26 of the flaps 4.
  • a stiffening rib 28, 30 projects from a rear surface of each segment 14, 16, transverse the central rib 12.
  • the central rib 12 has a tab 32 which is intended to abut the base 2 of the box.
  • the central rib 12 and the lateral ribs 18 are formed integrally with a flat support base 34 which is perpendicular to the axis A of the rib 12.
  • the base 34 forms a support for a corresponding upright of a superposed box.
  • Two diverging walls 36 project from the base 34 for laterally restraining and guiding the corner of a superposed box.
  • the same type of upright 10 can be used both for boxes with tall side walls, of the type shown in FIG. 1, and for boxes with low side walls of about half the height of the upright 10.
